[UIKit] Updated UIKit to xcode8-beta6

Expected extrospection test failures:

- ios.unclassified:!missing-field! UIApplicationInvalidInterfaceOrientationException not bound

Generator bugs:

- HACK: We have a generator bug(?) that won't allow overloads (AmbiguousMatchException) in protocols

tvOS/iOS 9 Introspection Expected failures (UIKit Only):

- [FAIL] UIKit.UIContentSizeCategoryExtensions.UIContentSizeCategoryUnspecified
Generated enum extensions do not honor availability on NSString properties

API Diff, expected changes (verified and correct):

Type Changed: UIKit.UIContentSizeCategory

Modified fields:

	ExtraExtraExtraLarge = 6 7
	ExtraExtraLarge = 5 6
	ExtraLarge = 4 5
	ExtraSmall = 0 1
	Large = 3 4
	Medium = 2 3
	Small = 1 2

Added values:

	AccessibilityExtraExtraExtraLarge = 12,
	AccessibilityExtraExtraLarge = 11,
	AccessibilityExtraLarge = 10,
	AccessibilityLarge = 9,
	AccessibilityMedium = 8,
	Unspecified = 0,
